1. How many degrees can the water temperature of solar water heaters reach?
Solar water heaters are divided into vacuum tubes and flat plates, and the temperatures are also different:< /p>
1. Vacuum tube water heater: water temperature in summer It can reach about 60℃, and the water temperature can reach about 45℃ in winter. She cannot adjust the temperature by herself. If it is heated continuously, it consumes. more power than ordinary electric water heaters.
2. Flat Panel Solar Water Heater: The water temperature can reach over 90℃ in summer and around 70℃ in winter. The water temperature of this type of water heater can be adjusted by itself. can save 70-90% energy compared to ordinary water heaters.
2. What problems should you pay attention to when using solar water heaters?
1. If you notice a water shortageWhen using solar water heaters, remember to refill water immediately. . Since the temperature inside the solar water heater tube will rise up to 2500°C during the air drying period, if the water is filled immediately, the tube may explode.
2. If there is an auxiliary heat source, it is recommended to regularly check whether the auxiliary heat source can work normally. When using it, you should also consider whether the protector is reliable. After starting the water heater, the water content in the tank cannot be less than 50%.
3. When installing heating tape on a solar water heater, pay attention to whether the quality of the heating tape is acceptable to avoid unnecessary safety risks. In addition, when the voltage is unstable, the electric heating tape cannot be used to avoid some safety accidents.otherwise it will cause inconvenience and problems.
What should I do if the water temperature of the solar water heater is too high in summer?
How to use and maintain water heaters correctly solar in summer:< /p>
1. Scientifically choose the water filling time
Solar water heaters should be filled with water regularly. However, it is strictly prohibited to fill the water when the weather is particularly hot and the water temperature is particularly high. It is strictly prohibited to add water immediately after the water is used up. Due to the strong sunlight in summer, the temperature of solar vacuum tubes in the air reaches 270 degrees Celsius to 400 degrees Celsius. At this time, it is easy to burst the vacuum tube. in the morning before sunrise or two hours after sunset in the evening. Water, it can guarantee the life of the v tubesolar idea.
2. Correctly adjust the hot and cold water valve
The steps of adjusting the water temperature of the solar water heater: first open the cold water valve, adjust the water flow cold water appropriately, then open the hot water valve and adjust until the required bath temperature is obtained.
Due to the prolonged duration of sunshine in summer, the temperature is higher and household hot water consumption is lower. Therefore, hot water from solar water heaters often has a higher temperature, usually reaching over 60 degrees Celsius. For ordinary households, the distance between the water storage point and the solar water heater water point is often long, the water temperature in the water pipes can reach about 35 degrees Celsius due to high temperature in summer. Therefore, when we turn on the water heater, the hot water at no temperatureThe malfunction in the water pipe will be discharged first, and after a minute or two, the high temperature hot water will be discharged. If you are not careful, you may burn yourself. your skin. Therefore, when using a water heater in summer, you should pay attention to the hot water temperature.
3. Intelligent use of tail hot water
Intelligent use of tail hot water can better save resources. When you take a shower, if the water in the solar water heater is used up and the person has not rinsed it, you can pour cold water for a few minutes and use the principle of flowing cold water and hot water floating to get out. hot water into the tube, and you can continue to shower; If there is still some hot water left in the solar water heater after showering, add cold water for a few minutes, and the resulting hot water will be able to fill it.see one more. person ; In addition, be careful not to point the nozzle towards the human body when adjusting the shower water temperature to avoid burns.
4. Appropriately determine the amount of water to be supplied
Determine the amount of water to be supplied based on weather conditions to achieve a more satisfactory water temperature. If the weather is good the next day, l water can be filled. ; if it is cloudy or cloudy, fill the tank with half a tank of water; it rained all day, so the original water was retained and no cold water was provided.
5. Check and maintain the pipes regularly.
Check the exhaust holes regularly to ensure smooth flow to avoid inflation or deflation of the water tank; For solar water heaters equipped with auxiliary electric heating devices, pay special attention to the water supplyto avoid drying out. burning without water. At the same time, check whether the solar water pipe insulation layer and UV-resistant tape are aging and cracking. If the water supply pipe is exposed, it will easily become hard, brittle, crack and leak under exposure to sunlight. Users are advised to install layers of insulation and UV tape beforehand to completely protect the water pipes.
6. Prevent accidents during thunderstorms and wind.
Due to their working principle, solar water heaters should be installed on the upper balcony. Solar water heaters are generally larger due to their heat collection requirements. Therefore, users should pay attention to reinforcing the supports of solar water heaters in windy weather to avoid accidents. Be sure to fill the water heater with water on windy days to increase stabilitylity.
7. Protective measures should be taken when the solar water heater is not used for a long time in summer.
Currently, most domestic solar water heaters use vacuum collector tubes. This type of vacuum collector tube has high absorption efficiency. When the outdoor temperature is high in summer, during seasons with long sunshine and strong radiation, it does not take 48 hours to reach the boiling point. If the water heater is not used for a long time, the water in the water tank will be retained for a long time. When the water tank is exposed to high temperatures for a long time, the aging rate of the polyurethane insulation layer will increase. Tartar will form easily. Excessive pressure will also cause the water tank to deteriorate, causing damage to the water tank.
Consequentlyt, if you do not use the solar water heater for a long time, you should cover the vacuum collecting tube and remove it when using it again. You can also remove the vacuum collector tube first, but this method cannot be done by yourself and requires professional assistance.
Water should be added at any time.
Usually, the temperature in the water tank exceeds 100 degrees in summer, which is prone to rust. First of all, you need to prolong the habit of using hot water, including washing clothes, dishes, etc. and add water at any time to keep the water in the tank warm. The water is always full, which can lower the water temperature in the water tank and prevent scale.
If the hot water in the water tank still cannot be used, the water temperature is too high. It is best to coverthe vacuum tube of the solar water heater with sunshade net and fix it firmly with ropes at four corners. The size of the sunshade net can be determined based on the water temperature.

Notes:
Installed those with Auxiliary heat sources should regularly check whether the auxiliary heat source device and heat exchanger are working properly. For auxiliary heat sources heated by electric heating pipes, you must ensure that the leakage protection device works reliably before use, otherwise it cannot be used. When using the electric auxiliary heater, special attention must be paid to filling the water. The volume of water in the water tank should not be less than 50% to avoid dry burning without water. DoPay particular attention to unplugging the power plug when taking a bath, and it is strictly prohibited to use it when it is powered on.
When installing the heating tape, be sure to choose products of acceptable quality to ensure normal use and reduce hidden dangers. When using the heating tape, be sure to turn it off promptly after defrosting, and try not to use it when the voltage is unstable.
